METHOD OF IDENTIFYING A TARGET USING A RADIO FUSE OF A MISSILE WITH A HOMING HEAD Russian patent published in 2020 - IPC F42C13/02 F42B15/01 F41G7/22 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment and can be used in creation of noise-proof proximity sensors of various ammunition targets, including missiles with homing heads on target. Method of identifying a target using a radio fuse of a missile with a homing head consists in that, using a radio fuse generator after time intervals T_i, short radio frequencies of duration τ (τ<<T_i) are generated in the radiating antenna of the radio fuse. Receiving antenna of radio fuse is used to receive radio pulses continuously in gating interval T_st. At that, using the radar station of the missile self-guidance head in real time for each time interval T_i the speed of approach of the missile is determined with the aim of V_sG. With channel information processing of radio fuse for each time interval T_i is calculated target distance S_i, using the relation S_i=ct_i/2, where c – velocity of light, t_i – time from the beginning of the radiation generator before the pulse in the information processing channel. For each two consecutive radiation periods, the rate of approach of the missile is calculated for the purpose of V_c, using the ratio V_c=(S_i-S_i+1)/T_i, where S_i+1 is the distance to the target in the next time interval t_i+1, for each time interval T_i. Comparing the calculated values of V_sG and V_c. From the ratio of the velocities identified taken during T_st strobe signals are reflected from the targets. Based on the comparison results, a decision is made to actuate the detonating fuse according to a predetermined algorithm.

EFFECT: invention increases noise immunity of proximity sensors of missile target using missile self-guided homing heads against artificial interference.
